Very easy with ruby:

require 'erb'

class AutomaticExercise

  attr_accessor :info

  def initialize(info)
    @info = info
  end

  def conditions
    if @info.has_key?(:conditions)
      return @info[:conditions]
    else
      return nil
    end
  end

  def satisfied_conditions(assignments)
    return eval(ERB.new(self.conditions).result_with_hash(assignments))
  end

  def numeric_value(assignments)
    if self.conditions != nil
      if self.satisfied_conditions(assignments) != true
        return nil
      end
    end

    r = Hash.new

    @info.keys.each do |k|
      r[k] = ERB.new(@info[k]).result_with_hash(assignments)
    end

    return r

  end

end

e = AutomaticExercise.new({:text => "Sum <%=a%>+<%=b%>", :solution => "<%=a+b%>", :conditions => "<%=a%> > 0"})
puts e.conditions.class
puts e.info
puts e.satisfied_conditions({:a => 5})
puts e.satisfied_conditions({:a => -1})
puts e.numeric_value({:a => 2, :b=>3})
puts e.numeric_value({:a => -1, :b=>3})

We avoid complexity of jinja templates. ERB is easy.

Perhaps ruby is more suitable, because it has ERB in default library.

One possibility is to put format field in AutomaticExercise class

With jinja2:

import automathlib
import fractions
 e.NumericValue({'a': fractions.Fraction(1,2), 'b': 3})
{'text': 'Calculate the sum of 1/2 and 3', 'solution': '7/2', 'resolution': '7/2'}

There is no ideal template, like ERB in ruby, which having all we need. We have to prioritze what we want.
